Hello ede_pt; Siemens has introduced in Step 7 V5.x a series of instructions to handle tables (such as FIFO and LIFO) from the TI series of PLCs. The library is named TI-S7 coverrting instructions. Have a look at this FAQ; you must use the online help to read about these functions a see how each one affects your project tables. For example, use ATT (FC 84) to add a value to an existing table, use FIFO (FC 85) to output the oldest value in the table, use LIFO (FC 86) to return the latest value added to the table... Management of tables in STEP 7 This documents shows where tom locate the library and what instructions it contains: What should you watch out for when converting from TI programs to S7 programs? Hope this helps, Daniel Chartier |
